B. luridus

Boletus L.

Recent molecular studies have shown that Boletus in its current circumscription is likely an artificial grouping and it is possible that it will be split at some point into smaller genera. Note that Boletus impolitus and Boletus depilatus for practical reasons are retained here, although there is strong evidence that they are closely related to Xerocomus subtomentosus and its allies.

Fruitbody large to medium sized, boletoid, without veil and ring. Stipe solid, with surface usually covered with granules or network. Flesh variously coloured, changing or not when exposed to air. Tubes easily separable from each other, not tearing apart. Pores usually small and rounded.

Similarity.Boletus luridus differs from all the other European boletes on the account of the vinaceous, red or orange red flesh under the tubes when these are removed. Compare more closely with Boletus queletii, which has yellow flesh under the tubes and does not have network on the stipe.

Variability. Extremely variable and few infraspecific taxa are sometimes recognized:
